Thanks for sending floppy image.

This floppy image contains following directory entry:
(this floppy image forgot testing extension name)

  name                   attribute                         used direntry
-----------------------------------------------------------------------------
LINUP    LONG_FILENAME, CASE_LOWER_BASE | CASE_LOWER_EXT         2
LINLOW                , CASE_LOWER_BASE | CASE_LOWER_EXT         1
DOSUP                 ,                                          1
DOSLOW                ,                                          1
98UP                  ,                                          1
98low    LONG_FILENAME,                                          2
W2KUP                 ,                                          1
W2KLOW                , CASE_LOWER_BASE                          1
NTUP                  ,                                          1
NTLOW                 , CASE_LOWER_BASE                          1

linux-2.4.8-pre8:
-----------------------------------------------------------------------------
LINUP                 , CASE_LOWER_BASE | CASE_LOWER_EXT         1
linlow   LONG_FILENAME, CASE_LOWER_BASE | CASE_LOWER_EXT         2

default, convert the shortname to lowercase:
  $ mount -t vfat fdd_vfat /mnt -o loop
  $ ls /mnt
  98low  98up  LINUP  doslow  dosup  linlow  ntlow  ntup  w2klow  w2kup

nocase option, use the win9x rule for display (doesn't support CASE_* flags):
  $ mount -t vfat fdd_vfat /mnt -o loop,nocase
  $ ls /mnt
  98UP  98low  DOSLOW  DOSUP  LINLOW  LINUP  NTLOW  NTUP  W2KLOW  W2KUP

2.4.8-pre8 is useing the win9x rule for create. But attribute must
change to 0.

Now, I writing the lower/win95/winnt/mixed rule on -ac tree.
Please help to test the following patch, if you interests.
